Hello,
To verify unknown user accounts on Big-IP F5 systems, check /var/log/secure for authentication logs and /config/bigip_user.conf for user account details. If these accounts are not tied to system processes or critical configurations, deleting them should only affect their ability to log in. Ensure you have backups and consult your organization's security policy before proceeding.

    Hi David

    I checked those and all I see is myself, the  /config/bigip_user.conf show those accounts configured but nothing more.  These accounts where here prior to me coming on board so just wanted to make sure this was just a regular user account before I delete it.  I know the defaults are Root and Adim, I see those there.

     

    Thank you
